These veins are distributed accordi

These veins are distributed according to physical and chemical laws. If they had solidified along a rift in the Earth, the atoms would have clumped together into long rings, or bands, layer upon layer, surrounding the granite melt. A belt of minerals now found on the earth's surface, a belt running from California through North and South America, is rich in lead, zinc, and silver; One runs north and south through Africa; A garland hundreds of kilometers long surrounds the hard rock of Asia, containing many minerals and colored stones.The distribution of the earth's mineral deposits seems to be haptic, as if there is no definite law, but now under the guidance of science, the distribution of mineral deposits has become a very regular atomic distribution map. From the principle that the properties of atoms determine their distribution in the earth's crust, we can solve many problems.
